摘　　要：研究了一种应用于电气化铁路的单相和三相组合式变压器供电系统.分析了单三相组合式供电系统的结构和工作原理,以及容量利用率和负序特性.使用Matlab/Simulink首先对单三相组合式供电系统的变压器进行了仿真,仿真结果表明,单三相组合式供电系统的结构和原理符合理论分析.其次,对组合式变压器构成的同相供电系统进行了仿真验证,仿真结果表明补偿方案是有效的.In this paper, one single and three phase combined transformer power supply system applied to e- lectrified railway was studied. The structure and principle of single and three phase combined power supply system and the negative sequence were analyzed. Matlab/Simulink is used to simulate the traction transformer and the compensation scheme. The simulation shows the correctness of the analysis of single and three phase combined power supply system. It also shows the compensation scheme for single and three phase combined co-phase supply system is effective.
